Check Digit Verification of cas no

The CAS Registry Mumber 139686-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,8 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139686-92:
(8*1)+(7*3)+(6*9)+(5*6)+(4*8)+(3*6)+(2*9)+(1*2)=183
183 % 10 = 3
So 139686-92-3 is a valid CAS Registry Number.
